Hi guys, well, i was wondering how this "technique" (from chum kiu form) was named because i've seen some names around like "ding sau / piercing hand", te guy in the images names it "chuen kiu / piercing arm" but i don't know if it's really correct
1st movement

HmorenoM , okay I ' ll share my own version about this technique with you the 1st move is basically chopping down or slicing down , what this technique does is that for example your opponent throws a low punch to your stomach area with his right hand you can use your left hand to slice down or chop down into his attacking hand , and you can apply any strike with your other hand .
2nd movement
